WESTERN AUSTRALIAN COASTAL NEWS
ISSUE 03  |  MAY 2020  |

WELCOME FROM THE CHAIR
 

Welcome to the Autumn edition of WA Coastal News.

Following the release of our Summer edition (Feb 29th 2020), there was a flurry of attention placed on the coast, and in particular on the issue of coastal erosion. This was in part due to a publication in Nature Climate Change that estimated approximately 50% of Australia’s sandy coastline would be lost by the year 2100. However, as the impacts of COVID-19 were felt in Australia attention rightly shifted to managing our health and economy.  As we slowly navigate towards a post COVID-19 Australia, we can re-focus our attention on the coast and consider the lessons and opportunities that can be taken to deliver positive outcomes for our coastline. 

This is timely given the severe erosion experienced only days ago. The impacts, while devastating in some locations, could have been far worse if the storm had passed 12-hours later on high-tide. Storm erosion events like this, while not new, highlight the importance of coordinated and inclusive discussions regarding how we manage erosion into the future – that is, discussing the what (what is vulnerable), why (which values we seek to protect), where (in which locations), for whom (who benefits) and how (protect, accommodate, retreat).

There are a number of exciting initiatives underway that may contribute to these discussions, from opportunities for community groups to co-produce science that addresses issues of import to local areas, to contributing to the national discussion on how to achieve a collaborative approach to erosion and inundation risk management in Australia (please have your say by completing the survey).  More locally, the next meeting of the WA Coastal and Marine Community Network will be hosted online and is scheduled for early July.  Make sure you are on our mailing list to keep up-to-date.

Finally, a big thank you to everyone that contributed content and supported the production of this issue. The collective effort has delivered an information rich edition - happy reading!

ACS WA Highlights: What has happened this season?
  • Planning has commenced for the next Coastal and Marine Community Forum – an online event planned for early July. This is in place of the initially proposed April forum, which did not eventuate due to COVID restrictions. We look forward to working with CoastSWaP and Perth NRM to host the next forum and see the network grow.
  • ACS WA has been in discussions with government, researchers and coastal experts to explore opportunities to progress a State-wide coastal data hub, which was a recommendation from the CMCN forum.
  • ACS WA is working with members of National board on the next ACS National Strategic Plan.

GOVERNANCE

 

Coastal Erosion and Inundation: What are your views?

 
At the 9th meeting of environment ministers in November last year, coastal erosion and inundation were acknowledged as risks that require a collaborative approach from all levels of government. Ministers agreed to establish an intergovernmental working group to collate existing information on coastal erosion and inundation hazard risk management and propose a collaborative approach to coastal erosion for consideration through a future meeting of environment ministers.
 
ACS is seeking to ensure the views of a range of coastal stakeholders are obtained as input into this process. To facilitate this, a short survey has been prepared (5-10 mins). You can complete the survey as an individual or as a representative of an organisation. If you would like to do both, complete and submit one survey, then open and complete a second survey.  
 

Implementing Managed Coastal Retreat in WA

 
Managed retreat may soon commence in WA, with a proposal to implement progressive removal of shack leases in Wedge and Grey (Shire of Dandaragan) based on shack distance from the shore and structural integrity. Protection measures are prohibited. 

 

Who or what is the CHRMAP forum?

 
CHRMAP is an acronym termed by the State Government which stands for ‘Coastal Hazard Risk Management and Adaptation Planning’. In 2017 a group of Local Governments in Western Australia established the Local Government CHRMAP Forum (WA). The forum was established for Local Government staff to discuss and resolve common issues being experienced when preparing and implementing CHRMAP plans.
 
The CHRMAP forum is hosted by the WA Local Government Association and meets every three months. Guest speakers are invited to share their expertise on a particular focus area at each meeting. Previous focus areas include: hazard mapping, sea level rise projections, managed retreat, coastal monitoring, and planning tools. Participants also present updates from their local area and key lessons for sharing with the group.  The CHRMAP forum also works together with the State Government, such as in 2017 when members made a combined contribution to the revision of the WA CHRMAP Guidelines. The group also works together to combine resources to seek specialist advice on common topics.
 
The forum has grown substantially from its humble beginning and now regularly attracts up to 30 participants from Local Governments across WA, both in-person and online. This growing forum demonstrates that WA Local Governments are actively working together to meet the significant challenge of preserving Western Australia’s unique coastline for future generations in an era of increasing sea levels.
 
For further details on the forum contact Ashley Robb or Garry Middle via planning@walga.asn.au

 

A State Policy on Climate Change

 
The State Government is currently developing a new State Climate Policy. The policy aims to help Western Australia adapt to the impacts of climate change, protect the environment, economy and the community, and contribute to national emissions reduction targets. It is anticipated that the Policy will also provide an opportunity to support recovery from the impact of the COVID-19 pandemic.  How? By ensuring new infrastructure projects are resilient under future climate scenarios, by providing support for emerging clean industries and jobs, and enhancing the capacity of regions to participate in the low carbon economy. It is expected that the State Climate Policy will be finalised and published before the end of 2020.

RESEARCH

 

Co-producing science for local impact

Future Earth, in partnership with the American Geophysical Union’s (AGU) Thriving Earth Exchange, is supporting a series of community science projects for sustainability, where communities and scientists co-produce actionable science to address a local or regional concern. This is a great opportunity for local communities to directly engage with scientists to address topics of local concern; for example, ocean and coastal adaptation to environmental and climate change [Future Earth Australia is collaborating with AGU, so Australian projects are eligible]. See the website for more details, or contact Eleanor Robson. Expressions of interest close on 26 June, so get in quick!
 

Coastal governance in Australia

This project, led by Prof Tim Smith from the University of the Sunshine Coast, is examining coastal governance in Australia and opportunities for innovation in the way we conceptualise and manage coast vulnerability.  The recently published project website has a range of open-access publications relating to the themes of coastal governance. www.usc.edu.au/coastalgovernance 
 

CoastSnap Update

The Peron Naturaliste Partnership (PNP) has partnered with the University of Western Australia to implement the first ‘CoastSnap’ project in Western Australia. CoastSnap, which started in NSW, is now a successful global initiative that engages and involves the community in scientific and environmental research to monitor changing coastlines. Members of the community take photos of beaches from a fixed smartphone camera stand, which are then uploaded, shared via social media and / or emailed to a database.  In addition to providing qualitative information of the along-coast morphology and beach state, beach width measurements and shoreline position can be extracted. Decision makers and coastal researchers can also use this data to investigate how the beach changes during extreme conditions, or in response to the long-term effects of climate change.
 
The CoastSnap sites include vulnerable coastal locations in each of the nine PNP member Local government areas. You can view photos submitted by citizen scientists on the CoastSnapWA Facebook page www.facebook.com/CoastSnapWA. For further information visit www.peronnaturaliste.org.au

The recently elected board, which consists of many new members including the chair, is detailed here.

 
Five-Year Study Quantifies How Sediment and Light Affect Coral.

Results from the culmination of five-years of groundbreaking research, to understand how dredging and sediments affect corals, will assist in quantifying the hazard and risk to corals of light reduction caused by suspended sediment in the water column. By describing the primary cause-effect pathway, the authors have quantified the relationship between suspended sediment, water quality and coral health and this can be used to guide management intervention. The study results also allow a much better understanding of the spatial effects associated with dredging.

 
WA's largest marine environmental information database was launched in March

WA’s capability to respond to environmental pressures including marine heatwaves, oil spills and fish kills, has been significantly improved by the development of a ground-breaking initiative that will see hundreds of millions of dollars’ worth of government and industry survey information made publicly available. The Index of Marine Surveys for Assessments (IMSA) is an online portal that provides free access to vast amounts of information about marine-based environmental surveys in WA. It is a project of the Department of Water and Environmental Regulation, developed in partnership with the WAMSI, for the capture and sharing of marine data created as part of environmental impact assessments (EIA).

COMMUNITY


A new use for Photomon

 
NACC NRM’s smartphone app, Photomon, was developed in 2013 to assist the community and coastal managers in monitoring coastal processes using photos of their local beaches. However, the app is also useful for comparing and monitoring an array of on-ground projects including revegetation and weed control along the coastline. Read the full story on NACC’s website.

National Volunteer week 18-24 May
(written by Carolyn Bloye, ACS WA Member).

With National Volunteer week just behind us, now is the time to think of, and thank, our wonderful volunteers. As WA slowly emerges from imposed isolation, and with the WA Premier’s focus on the state’s economy and getting people back to work, we should recognise the contribution of volunteers who play a major role in WA's economy and will be vital in its recovery.
 
Volunteers across the state have been required to isolate from activities they love and the human interaction volunteering provides. At this time coastal volunteers are usually busy weeding, realigning safe pathways through dunes, preparing areas for planting, or part-way through rehabilitation projects.  Soil deep in the dune is now at the right temperature and follow-up rains through the end of May and June ensure greater plant survival rates.  Nurseries that provide coastal tube stock organise their schedule to have seedlings ready for delivery in May/June. Unfortunately many of these projects will need to be deferred due to COVID-19.
 
Teams of committed volunteers will be cleaning up and rehabilitating after recent storms washed debris downstream, which eroded river banks and riparian vegetation, and caused high tides that eroded dune systems.
 
So here is a shout out to all our Great Volunteers – Happy National Volunteer week!     

EVENTS

 
Coastal Marine Community Network Forum #2: The next meeting of the Coastal and Marine Community Network will occur online (via Zoom) in early July 2020. Short presentations will provide an update of activities since the groups's inaugural meeting in February, and be followed by breakout activities to explore future opportunities for the group.

COASTAL NEWS FROM HOME AND ABROAD 


Our backyard - WA coastal news
 

In early May, an article in watoday described how the temporary rock ‘wall' at Port Beach (Fremantle)  passed its first true test after the first big storm of the season hit the coast earlier in the month.  The State government contributed $200,000 to building the structure, after the area was identified as a coastal erosion hotspot.

ABC news reports on the more recent impacts of ex-cyclone Mangga along the WA coast, including an interview with Professor Charitha (Chari) Pattiaratchi from the University of Western Australia. The Port Beach seawall also features strongly in this article.
 
In February, the ABC published an article on the redevelopment of Indiana Teahouse in Cottesloe. The project was halted following 'mixed' public feedback to Andrew Forrest, who purchased the property last year.
 

 
Our nation - Australian coastal news
 

 Erosion from recent storms was reported in Victoria on watoday. Sand walls  and fences have been swept away in Inverloch, an erosion hotspot 150 kilometres from Melbourne, and Apollo Bay 200 kilometres to the southwest.
 
In March, the release of a publication in Nature Climate Change, on global coastal beach erosion, projected the loss of almost half of the world's sandy beaches by the end of the century, although a moderate reduction in greenhouse gas emissions could prevent 40% of shoreline retreat. The Conversation reminds us that the rate of sea-level rise has accelerated by half since 1993 and is continuing to accelerate from rising greenhouse gas emissions. An article in watoday based on this research states that more than 12,000 kilometres of Australia's sandy beaches are threatened by coastal erosion by 2100, with greater losses predicted in northern Australia. ABC news indicates that we need to start planning now for the coastal retr.
 
Transforming tiny algae into coral superheroes. The Anthropocene Magazine reports on research where, over the course of 120 generations, researchers bred algae to be more heat-tolerant — a quality it then passed to its coral hosts.
 

The world - International coastal news
 

Satellite data show that melting ice sheets in Antarctica and Greenland have contributed to 14 mm sea level rise in 16 years, an ABC science article reported in May. Professor Smith from the University of Washington calculated that “if all the melt observed in this study was to flood an area the size of Australia, we would all be wading through 66 centimetres of water”.
 
A study in Nature Scientific Reports in April, shows that projections of global sea-level rise by the end of the century are comparable in magnitude to today’s extreme but short-lived storm events, that substantially increase water level. The Guardian warns that the US coastal flooding regime that now occurs 'once in a lifetime ' could become a daily high-tide occurrence, if sea level rise is not curbed. In February 2020, The Guardian also reported that the pace of sea level rise accelerated at nearly all US coastal measurement stations in 2019.
 
Rising seas and worsening flooding are forcing many coastal communities to plan their retreat, including affluent neighbourhoods in Norfolk, Virginia. In April, the Washington Post reported that Norfolk’s Vision 2100 plan includes the city withdrawing from some neighbourhoods by making only “judicious” investments to protect homes from rising waters. The policy would not force residents to abandon neighbourhoods, but have them gradually decide to leave as the inconvenience of staying grows.
 
India and Bangladesh faced one of the deadliest tropical cyclones on modern record, ABC news reported in May. The Bay of Bengal was the most affected area.

PUBLICATIONS/REPORTS


In March, the Marine Conservation Society published a report examining ‘The impacts of bushfires on coastal and marine environments’. Nutrients, ash, debris, sediments and metals released during fires can be washed into waterways and remove the feeding and breeding areas of aquatic animals, undermine the breathing of filter-feeding animals, and change the physiology and behaviours of marine animals. The report reviews academic literature, media reports and various websites to summarise what we know, what we don’t know, and what we need to know and do about bushfire impacts on marine and coastal environments. It also provides recommendations for research, monitoring, management, recovery and restoration and protection and mitigation.

 
Peer-reviewed research for 2020


All the publications described below are freely available to access, just click on the title (although the small number of papers in the box below will require paid access – but the abstracts are free!). Here we include papers addressing coastal or marine issues in Western Australia, Australia and Internationally – happy reading!
 


Western Australian Articles

 
The biogeomorphology of Shark Bay's microbialite coasts
This paper presents detailed results of the factors influencing the distribution of microbialites around Shark Bay (including 'stromatolites') and their environmental interactions. Detailed mapping of coastal ecological communities over multiple time scales provides the basis for identifying potential impacts of climate change, including variations in water level, temperature and ocean acidification. The authors conclude that research is urgently required to better understand the long-term maintenance of Shark Bay and uncertainties facing it.
 
Responses of corals to chronic turbidity
The paper presents the results from the culmination of five-years of groundbreaking research to understand how dredging and sediments affect corals. The results will assist in quantifying the hazard and risk to corals of light reduction caused by suspended sediment in the water column. By describing the primary cause-effect pathway, the authors have quantified the relationship between suspended sediment, water quality and coral health. This can be used to guide management intervention and understand the spatial effects of dredging.
 
Phytoplankton Responses to Climate‐Induced Warming and Interdecadal Oscillation in North‐Western Australia 
Decadal trends of phytoplankton biomass, reconstructed using diatoms and dinoflagellates,  showed a 1.5–3 times increase since the 1950s along a large section of the Kimberley coast. The authors  predict that the negative impact of rising ocean temperatures on phytoplankton in northwestern Australia could be buffered by increasing tropical cyclones and rainfall , which enhance nutrient supply favouring phytoplankton growth.
 
Modelling regional futures at decadal scale: application to the Kimberley region Ecosystem models were used to explore how to provide meaningful scientific information to support environmental decision making at the regional scale over several decades, in a network of marine parks in the Kimberley region of WA.  Results suggest that climate change, not economic development, is the largest factor affecting the future of marine ecosystems, with site-attached species at greatest risk and also the most likely to benefit from management strategies such as expanding sanctuary zones and Marine Protected Areas.
 
Microclimate modelling of beach sand temperatures reveals high spatial and temporal variation at sea turtle rookeries  
The authors contrast several types of models to predict beach sand temperatures, at depths relevant to sea turtle nesting, in order to explore thermal variation across mainland and island beaches in WA. Given that embryonic development of sea turtles is dependent on beach sand temperature, and temperature varies substantially between rookeries, reliably modelling thermal environments is imperative for conservation efforts, and can also be used to explore the impacts of climate change on sea turtle nesting.
 
Prioritising search effort to locate previously unknown populations of endangered marine reptiles (NW WA)
Lack of data is a significant limitation in conserving rare species like sea snakes, so the authors use data on five threatened endemic species of sea snakes to construct species distribution models to help prioritise locations for future field surveys. The models identified proximity to seagrass and reefs as important drivers of species presence. These factors were then used to identify a new location for an endangered sea snake – a first step in defining more robust extent of species occurrence and range overlap with threatening processes.
 
Non-song Vocalizations of Humpback Whales in Western Australia
The authors studied non-song vocalizations of humpback whales from two migratory areas off the WA coast: Geographe Bay and Port Hedland. They found that by expanding knowledge on the vocal repertoire of humpback whales they can improve their monitoring. In particular, the inclusion of non-song sounds in passive acoustic monitoring of humpback whales adds females and calves to the detection counts.
 
These Western Australian focused papers require institutional access or to be purchased, although their full abstracts may be viewed through the links provided: 
 
Multi-scale characterisation of stream nutrient and carbon dynamics in sandy near coastal catchments of south-western Australia.
The authors assessed the relative influence of catchment-scale land use and reach-scale vegetation structure on the distribution of carbon and nutrient concentrations of streams within urban and agricultural catchments of the Perth region, WA. They conclude that local riparian restoration can be a cost-effective strategy for managing excess nutrients and carbon in flat and permeable urban areas, particularly during low flow periods.
 
Nesting ecology of flatback sea turtles Natator depressus from Delambre Island, Western Australia 
Data on flipper tag re-sightings and track counts from flatback turtles on Delambre Island, WA were used to understand the environmental drivers of nest site selection, nest site fidelity, inter-nesting and remigration intervals. Sector of the beach was by far the strongest predictor of nest site, with turtles showing preference for the less exposed side of the island. The results will assist with future monitoring of this population and the management of threats related to coastal development and activities.
 
The diving behaviour of little penguins in Western Australia predisposes them to risk of injury by watercraft
Data loggers attached to little penguins on Penguin Island, WA were used to investigate the effect of recreational watercraft on penguins using coastal bays. The authors found that the risk of interaction from watercraft differs depending on penguin diving behaviour – predominantly shallow or deeper – and season, with a greater risk of injury during the summer and autumn, when people are more likely to use watercraft.
 
 
 

 

 
Australian Articles

 
Kelp Forest Restoration in Australia
Kelp forests in Australia are in decline due to ocean warming, overgrazing, and pollution which is alarming given their ecological importance and carbon-storage capacity.  The authors review methods, implementation and outcomes of kelp forest restoration, and discuss suitable measures of success and the estimated costs of restoration. Given the challenges of kelp restoration it is important to ameliorate the drivers of kelp decline and place a high value on conservation and protection of existing kelp forest ecosystems.
 
Charting two centuries of transformation in a coastal social-ecological system: A mixed methods  approach
Data on the abundance of the Sydney rock oyster was compiled from archaeological, anthropological and fisheries literature, and government and media accounts, to reconstruct the historical use of oysters, resource decline and management since Europeans arrived in eastern Australia. It demonstrates the application of historical information and context for contemporary management, protection and restoration of much-altered coastal social-ecological systems.
 
Using a resilience thinking approach to improve coastal governance responses to complexity and uncertainty: a Tasmanian case study, Australia
The authors identified crucial problems being experienced with the multi-layered Tasmanian coastal governance regime and found that resilience thinking provides a way to evaluate uncertainty and change: it is compatible with proactive and devolved leadership; it effectively considers issues of scale in the decision-making process; and, it can produce a hybrid resilience and risk-based approach to coastal management.
 
An evidence based approach to evaluating flood adaptation effectiveness including climate change considerations for coastal cities: City of Port Phillip, Victoria, Australia
An integrated model was used to analyse coastal and catchment inundation for the City of Port Phillip, Victoria. The authors suggest resources spent on adaptation infrastructure should factor in sea level rise for at least the next 50 years, and that conventional adaptation approaches will fail with a rise of around 0.4 m (a tipping point expected in the next 30 years).  Consequently, significant changes in infrastructure will be necessary, rather than incremental adaptation approaches to deal with future flooding.
 
The role of coastal processes in the management of the mouth of the River Murray, Australia:  Present and future challenges  (Abstract only)    
Prior to the regulation of the Murray–Darling River system, the Murray Mouth remained open to the sea even during droughts. Under current over-extraction of water resources upstream, river flows have been largely insufficient to counter wave and tide processes, which transport marine sands and constrict the river mouth.  Sea-level rise and decreased rainfall in the southern half of the Basin under climate change conditions will require a review of management options to prevent the long‐term degradation of the end of river system.
 
Trans-Tasman Cumulative Effects Management: A Comparative Study
Managing the cumulative effects that arise from human and natural stressors is one of the most urgent and complex problems facing coastal and marine decision makers today as they struggle to implement effective management strategies. By comparing Australia and NZ, the authors draw conclusions and establish priority actions regarding how to (1) mobilise resources and political will to address cumulative effects, (2) deal with data uncertainty and scarcity, and (3) promote comprehensive and inclusive coastal and marine management.

 

 

International Articles


Is ‘re-mobilisation’ nature restoration or nature destruction? A commentary   (dune management)
Due to an increase in coastal dune vegetation cover, especially in northern Europe, there has been a shift in the dune management paradigm to removing vegetation to promote bare sand habitat and species. The authors argue that such policies are unsustainable given current climatic and environmental conditions, as they can increase coastal erosion risks and force dune systems to deviate from adapting and changing to direct/indirect drivers; instead there are benefits from minimizing human impacts so that natural processes continue to occur.  Response to this article: https://link.springer.com/article/10.1007/s11852-020-00731-1
 
A capital approach for assessing local coastal governance
A framework to assess local coastal governance is developed and tested based on forms of “capital” (social, human, political, financial and environmental) to help local governments think reflexively about how they are managing the coast and the climate risks impacting on coastal assets and people.
 
The role of data within coastal resilience assessments: an East Anglia, UK, case study
This paper sets out to establish a set of core metrics and data sources suitable for inclusion within a data-driven coastal resilience assessment, rather than relying on theoretical modelling; the authors conclude this could facilitate more sustainable evidence-based management of coastal regions.
 
Building resilience in practice to support coral communities in the Western Indian Ocean
The authors explore the available evidence on strategies to build resilience of coral reefs, and reef-dependent communities, to global environmental and climate change.

Surging seas, rising fiscal stress: Exploring municipal fiscal vulnerability to climate change
Recent disasters and growing concerns about climate change have spurred calls for cities to retreat from and avoid developing in coastal areas. Instead, cities have doubled down on waterfront development. In this paper, the authors ask why and with what implications, using the U.S. state of Massachusetts as a case study.

Marine social sciences: Looking towards a sustainable future  (MARE workshop, global)
Paper concludes that social science needs to be embedded in all aspects of marine and coastal management in order to create truly sustainable solutions to the pervasive environmental challenges we face.
 
Shifted baselines and the policy placebo effect in conservation    (study area: Caribbean islands)
If the public prematurely perceives recovery, motivation for continued conservation could decline. Alternatively, perception of rapid success could lead communities to set more ambitious conservation goals.
 
Coastal heritage, global climate change, public engagement, and citizen science  (Scotland and USA)
The study compares methods of managing threatened coastal heritage sites especially those at risk from climate change, in order to help society, prepare for climate change impacts to heritage worldwide.
 
Citizen science provides added value in the monitoring for coastal non-indigenous species (Finland)
The outcomes of the study indicate that species-specific citizen observations can be a beneficial addition to supplement national monitoring programs to fulfil legislative reporting requirements and to target potential management. Citizen observations may enable distribution assessments for certain species that would otherwise require excessive resources and sampling efforts.
 
Design catalogue for eco-engineering of coastal artificial structures: a multifunctional approach for  stakeholders and end-users
After an extensive review, the authors suggest potential eco-engineering designs to enhance biodiversity and ecosystem functioning and services of artificial coastal structures, including: rock revetment, groynes and breakwaters; vertical and sloping seawalls; over-water structures (i.e., piers); and tidal river walls.
